The purpose of the study is to determine the bioavailability of orally administered folic acid compared with the i.v. administered folic acid, and to use the samples collected to validate ...
The purpose of the study is to determine the bioequivalence of Norgestimate (NGM) and Ethinyl Estradiol (EE) in 2 formulations of 250 mcg NGM/25 mcg EE, 1 without folic acid and 1 containi...
Periconceptional supplementation with folic acid - the synthetic form of the B-vitamin folate - reduces the occurrence of adverse pregnancy outcomes such as spina bifida. The underlying bi...
High levels of homocysteine, which is an amino acid in the blood, have been linked to an increased risk of heart disease. This study will examine the effect that differing levels of folic ...
The purpose of this study is to determine whether folic acid, alone or together with creatine supplementation, can lower blood arsenic concentrations and improve the ability to detoxify ar...
tRNA binding efficacy to folic acid-PAMAM nanoparticles was determined, using multiple spectroscopic methods, thermodynamic analysis and transmission electron microscopy (TEM). The structural analysis...
Consumption of high-dose folic acid supplements is common throughout pregnancy and lactation in several countries, including Canada, Brazil, and the United States, and may lead to high levels of circu...
Folic acid, a B vitamin, is vital for early neurodevelopment and is well known for its protective effect against neural tube defects. Various national health agencies worldwide recommend that women o...
Some medical practices have been ingrained in custom for decades, long after "proof" that they were effective was established. It is necessary to periodically reevaluate these practices, as newer theo...
Spina bifida and anencephaly are largely preventable birth defects through mandatory folic acid fortification. Our objective was to estimate the proportion of folic acid-preventable spina bifida and a...
The active metabolite of FOLIC ACID. Leucovorin is used principally as its calcium salt as an antidote to folic acid antagonists which block the conversion of folic acid to folinic acid.
Cell surface receptors that bind to and transport FOLIC ACID, 5-methyltetrahydrofolate, and a variety of folic acid derivatives. The receptors are essential for normal NEURAL TUBE development and transport folic acid via receptor-mediated endocytosis.
Derivatives of folic acid (pteroylglutamic acid). In gamma-glutamyl linkage they are found in many tissues. They are converted to folic acid by the action of pteroylpolyglutamate hydrolase or synthesized from folic acid by the action of folate polyglutamate synthetase. Synthetic pteroylpolyglutamic acids, which are in alpha-glutamyl linkage, are active in bacterial growth assays.
A nutritional condition produced by a deficiency of FOLIC ACID in the diet. Many plant and animal tissues contain folic acid, abundant in green leafy vegetables, yeast, liver, and mushrooms but destroyed by long-term cooking. Alcohol interferes with its intermediate metabolism and absorption. Folic acid deficiency may develop in long-term anticonvulsant therapy or with use of oral contraceptives. This deficiency causes anemia, macrocytic anemia, and megaloblastic anemia. It is indistinguishable from vitamin B 12 deficiency in peripheral blood and bone marrow findings, but the neurologic lesions seen in B 12 deficiency do not occur. (Merck Manual, 16th ed)
